TOI-7510: A Sun-Like Star With Three Jupiter-Like Worlds

TOI-7510 is a G3 star located 812 light-years away. Its mass is 1.06 solar masses, its radius is 1.03 solar radii, and its temperature is 5720 K. The star's reported radius estimate is larger than the Sun's, but its reported temperature is cooler than the Sun's. Three planets orbit this host.

All three planets are Jupiter-like, a size class that exceeds 4 times Earth's radius. Each was discovered by transit, the method that detects a planet passing in front of its star and causing a small dip in observed brightness.

TOI-7510 b has a mass of 18.1 Earth masses, a radius of 7.31 Earth radii, and an orbital period of 11.5 days. Among the listed planets, it has the shortest year, the smallest radius, and the smallest reported mass. Its mean density is 0.255 g/cm³, 0.0463 times Earth's.

TOI-7510 c has a mass of 131 Earth masses, a radius of 10.8 Earth radii, and an orbital period of 22.6 days. Among the listed planets, it has the second-shortest year, the largest radius, and the second-smallest reported mass. Its mean density is 0.571 g/cm³, 0.104 times Earth's.

TOI-7510 d has a mass of 190 Earth masses, a radius of 10.5 Earth radii, and an orbital period of 48.9 days. Among the listed planets, it has the longest year, the second-smallest radius, and the largest reported mass. Its mean density is 0.899 g/cm³, 0.163 times Earth's.

Each planet's reported radius and mass estimates are larger than Earth's.
